Smalling has become a first-team regular under Louis Van Gaal this season and has now made 147 appearances over the past five seasons with the Red Devils.

He follows Michael Carrick in signing a new deal with United and the club are now looking to sign David De Gea, Phil Jones and Ashley Young down to new contracts before the summer, according to the Telegraph.

Spanish goalkeeper De Gea has been one of the Premier League‘s best players this season, but has been continually linked with a move to Real Madrid, and United will be desperate to get him to commit his future to the club in the coming months.

He has just over one year remaining on his current deal so if the Red Devils are unable to convince him to stay, they will likely cash in this summer to avoid him leaving on a free a year later.

Phil Jones and Ashley Young have both been key members of the team under Van Gaal and look set to be rewarded for their efforts with extensions on their contracts which are set to end next summer as well.
